Resumen
En este trabajo se presentan diferentes técnicas de filtrado o cancelación de interferencia armónica en señales de medición para la detección de fallas en motores eléctricos. El objetivo es eliminar de las señales de medición aquellas componentes producidas por la red eléctrica, dejando únicamente las componentes útiles para el diagnóstico de fallas. Para dicha aplicación se evalúa el diseño de filtros en el dominio de la frecuencia (tipo comb) y de técnicas multirate, de procesamiento digital en el dominio temporal.
